Left tackle: Rasheed Walker
Rasheed Walker struggled against the Lions, but let's be honest, who didn't? He held his own in his previous two starts, giving up zero pressures in Weeks 2 and 3, per Pro Football Focus. Walker has played well enough to deserve more opportunities as the starting left tackle while David Bakhtiari is out.
Left guard: Elgton Jenkins
Note: Sean Rhyan is the choice if Elgton Jenkins doesn't play.
Elgton Jenkins practiced on Thursday, which is a good sign for his availability this week. If Jenkins isn't ready to return, there's no way the Packers can stick with Royce Newman. Maybe Sean Rhyan isn't the answer, but they should at least give him a shot over Newman. Hopefully, Jenkins is healthy and left guard is no longer a concern.
Center: Josh Myers
Josh Myers hasn't made a great start to the season, but he provides solid play at center. The Packers could move Zach Tom there, but they may need him at right guard if Jon Runyan Jr. isn't healthy.
Right guard: Zach Tom
Runyan didn't practice on Thursday due to groin and ankle injuries. If he's out, the Packers should move Tom inside. He was excellent at guard last season and could actually give Green Bay an upgrade over Runyan.
Right tackle: Yosh Nijman
With Tom shifting inside, Yosh Nijman gets the start at right tackle. Nijman started 13 games last season and played well. Moving Tom to guard with Nijman starting at right tackle is how the Packers can get their best five linemen on the field.
